The Biosorption of Hazardous Safranin O and
Crystal Violet Dyes by Pyracantha coccinea Biomass
In the current world, the release of synthetic dyes
to peripheral water bodies is a globally threatening
environmental issue that is on the rise. Due to their
benefit of providing vibrant and instant colors, these
synthetic dyes are commonly used in several industrial
sectors including, textile, leather, paper, press, rubber,
and plastic industries (Saha, Chowdhurt, Gupta ve
Kumar, 2010; Chowdhury, Mishra, Saha ve Kushwaha,
2011).
Pyracantha cocinea is a dwarf bush that is resistant
against harsh weather conditions. It is an evergreen
plant that is grown all around the world. Commonly
known as scarlet fire thorn, it is mostly used in landscape
architecture.
The aim of this project is to develop a new, alternative,
efficient, and low-cost method for the removal of harmful
synthetic dyes that damage the ecological balance
and threaten the lives of living creatures. Biosorption
is the binding of contaminants like heavy metal or dye
molecules onto a biomass surface, the biosorbent, in
the suitable aquatic environment. Biosorption is the
adsorption performed by a biomass. Commonly confused
with absorption, adsorption is a physicochemical
process that involves the accumulation of one substance
onto the surface of another and this binding is referred
to as biosorption when performed by a biomass. Since
biosorption is a biological and inexpensive method, it
has become a popular research area over the past years

Safranin O and Crystal Violet dyes are poisonous
synthetic dyes that are commonly used in press and
textile industries. Despite their common usage, it is
scientifically proven that Safranin O and Crystal Violet
dyes show mutagenic, toxic, and carcinogen effect even
in trace amount. Therefore, it is environmentally crucial
